    Senior Javascript Developer

    United States - Last active: 1 month ago - Tests: 1 - Portfolio: 1

    Right now my main interest would be in building 2D games using Unity, but I'd be interested in other game development opportunities as well. I have a very solid work ethic, and am used to working 10-20 hours/week on side-projects in the evenings. My latest side-project, NetPegs, was recently released for Amazon Fire TV, Google Nexus Player, and PC/Mac. By day, I am a senior Javascript developer with many years of professional development experience, both in the browser, and on the server. I have experience starting new projects from scratch, and also converting existing software from server-side platforms over to single-page Javascript apps. Although I love doing Javascript development, I get enough of that at work. In my free time, I'm most interested in making games.
